A '*' before an LSP means the LSP is not established
A '*' before a Label means the USCB or DSCB is stale
A '*' before a UpstreamPeer means the session is in GR state
A '*' before a NextHop means the LSP is FRR LSP
Step 3 Establish the MP-IBGP peer relationship between the PEs.
# Configure PE1.
[PE1] bgp 100
[PE1-bgp] peer 3.3.3.9 as-number 100
[PE1-bgp] peer 3.3.3.9 connect-interface loopback 1
[PE1-bgp] ipv4-family vpnv4
[PE1-bgp-af-vpnv4] peer 3.3.3.9 enable
[PE1-bgp-af-vpnv4] quit
[PE1-bgp] quit
# Configure PE2.
[PE2] bgp 100
[PE2-bgp] peer 1.1.1.9 as-number 100
[PE2-bgp] peer 1.1.1.9 connect-interface loopback 1
[PE2-bgp] ipv4-family vpnv4
[PE2-bgp-af-vpnv4] peer 1.1.1.9 enable
[PE2-bgp-af-vpnv4] quit
[PE2-bgp] quit
After the configuration, run the display bgp peer command or the display bgp vpnv4 all peer
command, you can see that the BGP peer relationship is set up between the PE and the CE, and
the peer status is Established.

Step 4 Configure VPN instances on PEs and bind the instances to the CE interfaces.
# Configure PE1.
